Front-panel limit test
This example is set up to test a box of 100
Ω
±1 % and 100
Ω
±10 % resistors that you want to
separate manually. You can change values as needed to adapt the test to your needs.
Set up the test:
1. Press the
FUNCTION
key.
2. Under Source Current and Measure, select
Resistance
.
3. Press the
MENU
key.
4. Under Measure, select
Settings
.
5. Next to Limits, select
View
.
6. To enable limit testing, set the state to
On
for both Limit 1 and Limit 2.
7. Leave the Auto Clear setting at the default of
On
for both limits.
8. For Limit 1, set the Low Value to
90
Ω
.
9. For Limit 1, set the High Value to
110
Ω
.
10. For Limit 2, set the Low Value to
99
Ω
.
11. For Limit 2, set the High Value to
101
Ω
.
12. Select
OK
.
13. On the MEASUREMENT SETTINGS screen, set the Sense Mode to
4-Wire
. Leave other settings
at the default values.
Run the test:
1. Press the
HOME
key.
2. Use 4-wire connections to connect the first resistor to the instrument.
3. Press
Output ON/OFF
to turn the source on.
4. Verify that the instrument is set to Continuous Measurement. If necessary, hold the
TRIGGER
key for 3 seconds and select
Continuous Measurement
.
5. Observe the measurements. If the resistor is inside the limits set for Limit 1, L1PASS is displayed.
If the resistor is not within the limits, L1FAIL is displayed. If the resistor is in the limits set for Limit
2, L2PASS is displayed. If the resistor is not within the limits, L2FAIL is displayed. An example of
a test that passed the L1 test but failed the L2 test is shown below.
6. Press
Output ON/OFF
to turn the source off. Note that the limit indicators are displayed until you
turn limit testing off.
